Nice description of setting up there Dan.

I would like to add, I use Holley XP Ultra or Barry Grant Demon Idle-eze to trim idle speed on my carbs.
I set the primary and secondary to just above an appropriate minimum for the engine, and trim with the bypass valve.

One carb I built for a mate of mine I fitted a set screw to the primary side, so he doesn't mess with it. I taught him to trim the idle if necessary with the secondary.
It has a lot of scope, about 500 rpm, which he never needs. 260 @ .050 Roller cam 355 idles happily (EFI quality) at 850 rpm 8 inches Hg.
